Technical Field

[0001] The present invention relates to an optical element driving device, a camera module, and a camera-mounted device.

Background Art

[0002] Conventionally, a camera module mounted on a thin camera-mounted device such as a smartphone is known. Such a camera module is known to include an optical element driving device having an optical element that bends incident light along a predetermined direction toward the imaging element (see, for example, Patent Document 1).

[0003] The camera module has a shake correction function (OIS (Optical Image Stabilization) function) that optically corrects shake (vibration) generated during shooting and reduces image blur by rotationally driving the optical element according to the direction of incident light by this optical element driving device.

[0004] In the optical element driving device, for example, a configuration in which a movable part that holds the optical element is configured to be movable and the movable part is driven is generally known. A substrate part that can supply power to a drive source or the like that drives the movable part is provided on the bottom surface side of the movable part in the optical element driving device.

[0005] By the way, there may be a case where some power supply is performed inside the movable part. For example, when driving an optical element inside the movable part, it is necessary to supply power to a drive part provided inside the movable part. In this case, a power supply path part that constitutes a power supply path between the substrate part and the movable part is provided.

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figures 1A and 1B show a smartphone equipped with a camera module. Figure 2 is a simplified diagram showing a camera module 1 according to an embodiment of the present invention. Figure 3 is a simplified diagram showing a side view of the camera module 1 according to this embodiment.

[0015] Camera module 1 is mounted on thin camera-equipped devices such as smartphones M (see Figures 1A and 1B), mobile phones, digital cameras, notebook computers, tablet devices, portable game consoles, and in-car cameras.

[0016] In describing the structure of the camera module 1 in this embodiment, we will use a Cartesian coordinate system (X, Y, Z). The figures described later will also use the same Cartesian coordinate system (X, Y, Z). When the camera module 1 is actually mounted on the camera-mounted device, for example, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction. Light from the subject enters from the Z direction + side (positive side), bends, and is guided to the Y direction + side. By reducing the thickness of the camera module 1 in the Z direction, the camera-mounted device can be made thinner.

[0017] As shown in Figures 2 to 4, the camera module 1 comprises a housing 10, a circuit board 20, a cover 30, a cap 40 (see Figure 8, etc.), a mirror housing 50, a mirror holding 60, a power supply path 70 (see Figure 14, etc.), a drive control unit 100, a lens drive unit 110, and an imaging unit 120.

[0018] The drive control unit 100 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc. The CPU reads a program corresponding to the processing content from the ROM, loads it into the RAM, and works in cooperation with the loaded program to centrally control the first drive unit and the second drive unit, which will be described later. As a result, the drive control unit 100 drives the mirror housing unit 50 housed in the housing 10 and the mirror holding unit 60 held in the mirror housing unit 50.

[0019] In this embodiment, the mirror housing 50 is rotatable around the Y direction, and the mirror holding 60 is rotatable around the X direction. Therefore, the mirror element 61 held by the mirror holding 60 has rotation axes extending in the X and Y directions, and rotates around these rotation axes under the control of the drive control unit 100. As a result, the camera module 1 has an optical image stabilization (OIS) function that optically corrects shake (vibration) that occurs during shooting to reduce image distortion.

[0020] As shown in Figure 3, in the camera module 1, incident light L1 along the Z direction (first direction) is incident on the housing 10. The incident light L1 is bent by the mirror element 61 inside the housing 10 so that it travels on the positive side (one side) of the Y direction (second direction). A lens drive unit 110 is provided on the positive side of the housing 10 in the Y direction, and the reflected light L2 bent by the mirror element 61 is incident on the lens drive unit 110. The housing 10, substrate 20, cover 30, cap 40, mirror housing 50, mirror holding 60, and power supply path 70 correspond to the "optical element driving device" of the present invention. The housing 10, substrate 20, cover 30, cap 40, mirror housing 50, mirror holding 60, and power supply path 70 will be described later.

[0021] The lens drive unit 110 includes, for example, a first fixed lens 111, a first movable lens 112, a second movable lens 113, a second fixed lens 114, and a lens drive control unit 115. Within the lens drive unit 110, for example, the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114 are arranged in order from the negative side (minus side) in the Y direction. The reflected light L2 is output to the imaging unit 120 via the first fixed lens 111, the first movable lens 112, the second movable lens 113, and the second fixed lens 114.

[0022] The lens drive control unit 115 includes a CPU, ROM, RAM, etc., and controls the movement of the first movable lens 112 and the second movable lens 113. In the lens drive unit 110, under the control of the lens drive control unit 115, the first movable lens 112 and the second movable lens 113 move independently in the Y direction. As a result, the camera module 1 performs stepless optical zoom and autofocus.

[0023] The imaging unit 120 is positioned on the positive side of the lens drive unit 110 in the Y direction, and is configured to receive reflected light L2 via a first fixed lens 111, a first movable lens 112, a second movable lens 113, and a second fixed lens 114. The imaging unit 120 includes an image sensor and an imaging substrate (not shown).

[0024] The image sensor is composed of, for example, a CCD (Charge Coupled Device) type image sensor or a CMOS (Complementary Metal Oxide Semiconductor) type image sensor. The image sensor is mounted on an imaging substrate and electrically connected to the wiring on the substrate via bonding wires. The image sensor captures an image of a subject formed by a first fixed lens 111, a first movable lens 112, a second movable lens 113, and a second fixed lens 114, and outputs an electrical signal corresponding to the subject image.

[0025] Furthermore, a printed circuit board (not shown) is electrically connected to the imaging substrate of the imaging unit 120, and power is supplied to the image sensor and electrical signals of the subject image captured by the image sensor are output via this printed circuit board. These electrical signals are output to an imaging control unit 200 provided in the camera mounting device. The imaging control unit 200 is equipped with a CPU, ROM, RAM, etc., and processes the image information obtained by the camera module 1. The imaging control unit 200 may be mounted in the camera mounting device, but it may also be built into the camera module 1.

[0026] Next, the details of the housing 10, substrate section 20, cover section 30, cap section 40 (see Figure 8, etc.), mirror housing section 50, mirror holding section 60, and power supply path section 70 (see Figure 14, etc.) will be described. The housing 10, substrate section 20, cover section 30, cap section 40, mirror housing section 50, mirror holding section 60, and power supply path section 70 correspond to the "optical element driving device" of the present invention.

[0027] First, let's describe the housing 10. As shown in Figure 4, the housing 10 houses the cover portion 30, the cap portion 40, the mirror housing portion 50, the mirror holding portion 60, and the power supply path portion 70, and for example, has a rectangular parallelepiped shape as a whole. The housing 10 has an entrance wall 11, an exit wall 12, a pair of side walls 13, and a bottom wall 14.

[0028] The incident wall 11 is the wall on the positive side in the Z direction of the housing 10, and is located on the side into which the incident light L1 enters. The incident wall 11 is provided with an opening 11A for the incident light L1 to enter the interior of the housing 10. The opening 11A is located in a position corresponding to the mirror element section 61, which is housed within the housing 10. The length of the opening 11A in the Y direction corresponds to the length of the mirror's movement range in the Y direction (see Figures 28, 29, etc.).

[0029] As a result, even if the positional relationship of the incident light L1 with respect to the aperture 11A shifts due to vibrations during shooting, for example, the mirror element 61 moves appropriately under the control of the drive control unit 100, so that the incident light L1 that enters through the aperture 11A is bent by the mirror element 61 within the range of the aperture 12A, which will be described later.

[0030] The emission wall 12 is the positive side wall in the Y direction of the housing 10, and is located on the side from which the reflected light L2, which is emitted when the incident light L1 is reflected from the mirror element 61, is emitted. The emission wall 12 is provided with an opening 12A for the reflected light L2 to be output to the outside of the housing 10.

[0031] The opening 12A is formed in a substantially circular shape extending in the X direction. A circular arc-shaped guide groove 12B is provided on the Y-side surface of the ejection wall 12, extending around the rotation axis of the mirror housing 50 and running along the opening 12A (see Figure 14). The circular arc-shaped guide groove 12B is configured in a circular arc shape that is convex towards the Z-side (+ direction) and has a groove shape that tapers towards the bottom (Y-side). The ejection wall 12 supports the mirror housing 50 so that the rotation axis is aligned with the Y direction by having the circular arc-shaped guide groove 12B.

[0032] The pair of side walls 13 are the side walls on both sides in the X direction of the housing 10 and are integrally formed with the inlet wall 11 and the outlet wall 12. As shown in Figure 5, the end faces on the - side in the Z direction of the pair of side walls 13 are provided with engaged portions 13A into which the cover portion 30 engages.

[0033] The bottom wall 14 is the wall on the negative side in the Z direction of the housing 10. In other words, the bottom wall 14 is positioned on the side opposite to the incident side of the incident light L1 relative to the mirror housing 50 in the Z direction. The bottom wall 14 is detachably attached to the negative end faces in the Z direction of the pair of side walls 13. The bottom wall 14 is provided with a substrate portion 20 to which power is supplied from the power supply of the camera mounting device.

[0034] Next, the circuit board 20 will be described. The circuit board 20 is positioned along the Y direction, spaced apart from the mirror housing 50, and has a plurality of input / output terminals 21. The circuit board 20 is configured to input electrical signals from outside the housing 10 or output electrical signals from inside the housing 10. Of the plurality of input / output terminals 21, the input / output terminal 21A on the Y direction of the circuit board 20 is connected to terminal 12C, which enables power supply to and from the mirror housing 50.

[0035] Terminal 12C is inserted into the output wall 12 and is positioned to contact the input / output terminal 21A of the substrate 20 when the substrate 20 is mounted on the pair of side walls 13. Terminal 12C is connected to the mirror housing 50 via the power supply path 70 (see Figure 31).

[0036] This allows the circuit board 20 to supply power to the mirror housing 50. The circuit board 20 has three input / output terminals 21A on both the positive and negative sides. For example, the positive side input / output terminals 21A are located on the negative side in the X direction at the positive end in the Y direction of the circuit board 20, and the negative side input / output terminals 21A are located on the positive side in the X direction at the positive end in the Y direction of the circuit board 20.

[0037] Furthermore, the substrate portion 20 is provided with a resonant portion 22 which constitutes a first drive unit for rotating the mirror housing portion 50 around a rotation axis (first rotation axis) along the Y direction. Also, as shown in Figure 6, a contact portion 50A is provided on the negative side in the Z direction of the mirror housing portion 50, which applies preload to the mirror housing portion 50 by contacting the vibrating resonant portion 22, thereby driving the mirror housing portion 50 to rotate.

[0038] The resonant portion 22 and the contact portion 50A constitute an ultrasonic motor that serves as the first drive unit for rotational driving of the mirror housing portion 50 around the Y direction. Note that the first drive unit may be something other than an ultrasonic motor, such as a VCM (Voice Coil Motor).

[0039] Furthermore, a magnet section 50B is provided on the negative side (Z-direction) of the mirror housing section 50. The magnet section 50B has a configuration in which a north pole magnet and a south pole magnet are adjacent to each other in the X direction.

[0040] As shown in Figure 5, a position detection unit 23 is provided at a position on the substrate 20 corresponding to the magnet 50B. The position detection unit 23 is a magnetoresistive element or the like, capable of detecting magnetic force, and detects the magnetic force of the magnet 50B.

[0041] When the mirror housing 50 is rotated by the first drive unit around a rotation axis along the Y direction, the magnetic force of the magnet unit 50B detected by the position detection unit 23 fluctuates depending on the position of the mirror housing 50. In other words, the position detection unit 23 detects the position related to the rotational drive of the mirror housing 50 around the Y direction by detecting the change in the magnetic force of the magnet unit 50B according to the position of the mirror housing 50.

[0042] Next, the cover portion 30 will be described. As shown in Figures 6, 7, and 8, the cover portion 30 is the wall on the Y-side in the housing 10 and is configured to be detachably attached to the Y-side ends of the entrance wall 11 and the pair of side walls 13. The cover portion 30 has a main body wall portion 31, a resin portion 32, and a biasing portion 33.

[0043] The main body wall portion 31 constitutes the wall portion of the cover portion 30 and is configured in a rectangular shape capable of covering the opening portion formed by the incident wall 11 and the pair of side walls 13.

[0044] As shown in Figure 9, the resin part 32 is configured in the shape of a rectangular frame and is fixed to the main body wall 31 by fitting it into, for example, a rectangular protrusion 31A that protrudes from the + side surface in the Y direction of the main body wall 31. The resin part 32 has a protrusion 32A and an engaging part 32B.

[0045] The protrusions 32A are provided at both ends in the X direction of the positive side in the Z direction of the resin portion 32. The protrusions 32A are provided at positions corresponding to the recesses 13B provided in the side wall 13 described above, and fit into the recesses 13B.

[0046] The engaging portion 32B is provided at both ends in the X direction of the Z-side edge of the resin portion 32. The engaging portion 32B is located at a position corresponding to the engaged portion 13A provided at the Z-side end of the side wall 13 described above, and engages with the engaged portion 13A.

[0047] In this way, the protruding portion 32A fits into the recessed portion 13B, and the engaging portion 32B engages with the engaged portion 13A, thereby mounting the cover portion 30 to the housing 10.

[0048] The biasing portion 33 is a biasing member such as a leaf spring, and biases the mirror housing portion 50 toward the positive side in the Y direction by biasing the cap portion 40 toward the mirror housing portion 50. The biasing portion 33 is fixed to the main body wall portion 31, for example. As shown in Figure 10, the biasing portion 33 has an annular portion 331, an arm portion 332, and a connecting portion 333.

[0049] The annular portion 331 is located in the center of the biasing portion 33 in the X direction and is configured in an annular shape. The annular portion 331 is the part that contacts the cap portion 40 and has an outer shape that is approximately the same as that of the cap portion 40. When the cover portion 30 is attached to the housing 10, the annular portion 331 is located in a position corresponding to the cap portion 40.

[0050] The arm portions 332 are parts that extend in the X direction from each of the X-direction ends of the annular portion 331, and two are provided at each of the X-direction ends of the annular portion 331. The two arm portions 332 on one side (+ side or - side) in the X direction are connected by a connecting portion 333 at the end opposite to the annular portion 331 in the X direction. When a force is applied to these arm portions 332, for example in the Y direction, pressing the annular portion 331, a restoring force (biasing force) is generated that tries to return it to its original shape.

[0051] Furthermore, each arm portion 332 flanking the annular portion 331 in the X direction has a shape symmetrical with respect to the annular portion 331 in the X direction. This makes it possible to equalize the biasing force from the arm portions 332 on both sides in the X direction.

[0052] Furthermore, the two arm portions 332 on one side (+ side or - side) in the X direction have a shape symmetrical with respect to the annular portion 331 in the Z direction. This makes it possible to equalize the biasing force from the two arm portions 332 in the Z direction.

[0053] Next, the cap portion 40 will be described. As shown in Figure 11, the cap portion 40 is the part that covers the first sliding groove portion 512A at the Y-side end of the mirror housing portion 50, and is positioned between the mirror housing portion 50 and the cover portion 30 (biasing portion 33). The cap portion 40 is positioned in a location corresponding to the annular portion 331 of the biasing portion 33, and is configured in a circular shape similar to the outer shape of the annular portion 331 of the biasing portion 33.

[0054] As shown in Figure 12, an annular guide groove 41 is formed on the positive side in the Y direction of the cap portion 40, that is, on the side facing the mirror housing portion 50, extending around the rotation axis of the mirror housing portion 50. The annular guide groove 41 has a groove shape that tapers towards the bottom (negative side in the Y direction). By having the annular guide groove 41, the cap portion 40 supports the mirror housing portion 50 so that the rotation axis is aligned with the Y direction.

[0055] As shown in Figure 13, the cap portion 40 is positioned between the mirror housing portion 50 and the cover portion 30, causing the annular portion 331 of the biasing portion 33 to be pressed towards the negative side in the Y direction by the cap portion 40. This generates a biasing force (see arrow) that causes the biasing portion 33 to return to its original shape by the arm portion 332, causing the biasing portion 33 to bias the cap portion 40 toward the mirror housing portion 50. As a result, the biasing portion 33 biases the mirror housing portion 50 toward the positive side in the Y direction.

[0056] Next, the mirror housing section 50 will be described. As shown in Figure 14, the mirror housing section 50 is the part that houses the mirror holding section 60 in the camera module 1, and rotates around a rotation axis along the Y direction by the first drive unit described above. The mirror housing section 50 corresponds to the "movable part" of the present invention.

[0057] The mirror housing 50 is configured such that at least the outer shape on the negative side in the Z direction is an arc shape that is convex to the negative side in the Z direction. This makes the mirror housing 50 easily rotatable around a rotation axis along the Y direction. Furthermore, the mirror housing 50 is configured to be detachable from the housing 10 through an opening formed by the entrance wall 11 and a pair of side walls 13 of the housing 10 when the cover portion 30 is removed.

[0058] As shown in Figures 15 and 16, the mirror housing 50 includes a housing casing 51, a regulating cover 52, a housing side substrate 53, a first sliding part 54, a first spacing holding part 55, a second sliding part 56, and a second spacing holding part 57.

[0059] As shown in Figure 17, the housing 51 is a housing that houses the mirror holding part 60 and has a mirror guide part 511, a first sliding wall 512, a second sliding wall 513, a pair of side walls 514, and a pair of yoke parts 515. The housing 51 has a rectangular outer shape composed of the first sliding wall 512 and the second sliding wall 513 extending in the X direction and the pair of side walls 514 extending in the Y direction.

[0060] The mirror guide portion 511 holds the mirror holding portion 60 and guides the rotation of the mirror holding portion 60 around a rotation axis along the X direction. The mirror guide portion 511 is provided on the Y-side (first sliding wall 512) of the housing 51 in the portion enclosed by the first sliding wall 512, the second sliding wall 513 and the pair of side walls 514.

[0061] The mirror guide portion 511 is provided with a rotation guide groove portion 511A for guiding the rotation of the mirror holding portion 60. The rotation guide groove portion 511A has an arc-shaped guide surface that is convex in an oblique direction toward the negative side in the Z direction and the negative side in the Y direction (see Figure 19), and one is provided on each end in the X direction.

[0062] Furthermore, a resonant section 511B, which serves as a second drive section, is provided between the two rotating guide grooves 511A. The resonant section 511B is energized via a terminal 511C that is electrically connected to the housing side substrate section 53. In addition, a contact section 50A and a magnet section 50B, which serve as the first drive section described above, are provided on the negative Z-side of the mirror guide section 511 (see Figure 6).

[0063] As shown in Figures 16 and 18, the first sliding wall 512 is a side wall located on the Y-side of the housing 51, and is a wall that slides with the cap portion 40 via the first sliding portion 54 and the first spacing holding portion 55 when the mirror housing portion 50 rotates around a rotation axis along the Y-side. A first sliding groove portion 512A is provided in the center of the first sliding wall 512 in the X-side.

[0064] The first sliding groove 512A is configured in an annular shape, similar to the annular guide groove 41 of the cap portion 40 described above. The first sliding groove 512A is located opposite the annular guide groove 41 in the Y direction. The first sliding groove 512A has a groove shape that tapers towards the bottom (the + side in the Y direction).

[0065] Furthermore, the first sliding wall 512 is provided with a housing side base plate portion 53, and path holding portions 512B for holding the power supply path portion 70 are provided at both ends of the first sliding wall 512 in the X direction. Three path holding portions 512B are provided at each end in the X direction and are configured to hold each of the three power supply path portions 70.

[0066] As shown in Figures 15 and 17, the second sliding wall 513 is a side wall located on the + side in the Y direction of the housing 51, and is a wall that slides with the ejection wall 12 via the second sliding part 56 and the second spacing holding part 57 when the mirror housing 50 rotates around a rotation axis along the Y direction.

[0067] An opening 513A is formed in the second sliding wall 513 through which reflected light L2 from the mirror element is emitted. The opening 513A is configured in an arc shape that is convex to the + side in the Z direction, similar to the shape of the opening 12A of the emission wall 12 described above (see Figure 14). A second sliding groove 513B is provided on the + side in the Y direction of the second sliding wall 513, along the opening 513A.

[0068] The second sliding groove 513B is configured in an arc shape that is convex to the + side in the Z direction, similar to the arc-shaped guide groove 12B of the ejection wall 12 described above (see Figure 14). The second sliding groove 513B is located opposite the arc-shaped guide groove 12B in the Y direction. The second sliding groove 513B has a groove shape that tapers towards the bottom (the - side in the Y direction).

[0069] As shown in Figure 17, the pair of side walls 514 are provided so as to sandwich the mirror guide portion 511 in the X direction. Furthermore, as shown in Figure 19, the inner surfaces of the pair of side walls 514 are provided with a regulating portion 514A and a yoke arrangement portion 514B.

[0070] Since the regulating section 514A and the yoke arrangement section 514B have substantially the same shape on each of the pair of side walls 514, in the following description only the + side in the X direction will be described, and the - side in the X direction will be omitted.

[0071] The restricting portion 514A is a part that restricts the movement of the mirror holding portion 60 based on rotational drive, and is provided at the + side end in the Y direction of each side wall 514, protruding inward in the X direction from the side wall 514.

[0072] The yoke arrangement section 514B is the part in which each of the pair of yoke sections 515 is positioned, and is provided projecting inward in the X direction from each side wall 514. The yoke arrangement section 514B is configured in the shape of an arc that is convex diagonally toward the negative side in the Z direction and the negative side in the Y direction, along the mirror guide section 511 described above, and is provided at a position that projects further toward the positive side in the Z direction than the mirror guide section 511.

[0073] The pair of yoke portions 515 are yokes that form a magnetic circuit together with the magnet portion 623, which will be described later, and are arranged in each yoke arrangement portion 514B of the pair of side walls 514. The yoke portions 515 are configured in an arc shape that is convex in the diagonal direction toward the negative side in the Z direction and toward the negative side in the Y direction, along the yoke arrangement portion 514B. In other words, the yoke portion 515 has a first surface 515A that extends parallel in the X direction to the guide surface (rotation guide groove portion 511A, which is the positive side surface in the Z direction) of the mirror holding portion 60 in the mirror guide portion 511, and is concentric with the guide surface in the Y direction.

[0074] As shown in Figures 15 and 16, the restricting cover portion 52 is provided in the area between the pair of side walls 514 and the first sliding wall 512, and restricts the mirror holding portion 60 from coming out of the mirror housing portion 50. The restricting cover portion 52 has a first restricting portion 521 and a second restricting portion 522.

[0075] The first restricting portion 521 is positioned to cover the first sliding wall 512 from the Y-side. The portion of the first restricting portion 521 corresponding to the first sliding groove portion 512A is open. This portion is large enough for the cap portion 40 to pass through.

[0076] A first restricting wall 521A is provided at the positive Z-side end of the first restricting section 521. The first restricting wall 521A protrudes from this end towards the positive Y-side. This first restricting wall 521A restricts the movement of the mirror holding section 60 towards the positive Z-side (see Figure 28).

[0077] The second restricting section 522 extends from both sides of the first restricting section 521 in the X direction to the + side in the Y direction and is mounted so as to be resting on a pair of side walls 514. The second restricting section 522 is provided with a second restricting wall 522A that extends to the - side in the Z direction on the inside of the side walls 514.

[0078] This second restricting wall 522A restricts the movement of the mirror holder 60 toward the + side in the Z direction (see Figures 28 and 29).

[0079] Furthermore, a housing-side substrate portion 53 is provided in the portion of the first sliding wall 512 that is covered by the restricting cover portion 52. As shown in Figure 18, the housing-side substrate portion 53 is configured to engage with a projection that protrudes from the first sliding wall 512 to the - side in the Y direction. The housing-side substrate portion 53 has a main substrate portion 531 and an extended substrate portion 532.

[0080] The main substrate portion 531 extends from the path holding portion 512B on the negative side in the X direction to the path holding portion 512B on the positive side in the X direction. The main substrate portion 531 is cut out on the positive side in the Z direction in a portion corresponding to the first sliding groove portion 512A so as not to overlap with the first sliding groove portion 512A.

[0081] First power supply terminals 531A, which are connected to the power supply path section 70, are provided at both ends of the main circuit board section 531 in the X direction, that is, at the portions corresponding to the path holding section 512B. In this embodiment, three first power supply terminals 531A are provided at each end of the main circuit board section 531 in the X direction.

[0082] Furthermore, a second power supply terminal 531B is provided in the center of the main circuit board portion 531 in the X direction, which is connected to terminal 511C (see Figure 17) that is connected to the aforementioned resonant portion 511B.

[0083] The extended substrate portion 532 extends from the negative end in the X direction of the main substrate portion 531 along the side wall 514 to the positive side in the Y direction. A position detection unit 532A is arranged on the extended substrate portion 532.

[0084] The position detection unit 532A is a magnetoresistive element, for example, that can detect magnetic force. Also, as shown in Figure 17, a position detection hole 514C is formed in the side wall 514 on the positive side in the X direction, penetrating in the X direction. The position detection unit 532A is positioned at a location corresponding to the position detection hole 514C. As a result, the position detection unit 532A is positioned to face the mirror holding part 60 inside the housing 51, and magnetically detects the position of the mirror holding part 60 (magnet part 623).

[0085] As shown in Figures 16, 20, and 21, the first sliding portion 54 is a spherical member interposed between the annular guide groove portion 41 of the cap portion 40 and the first sliding groove portion 512A of the first sliding wall 512, and by being interposed between the cap portion 40 and the first sliding portion 54, it forms a surface that supports the mirror housing portion 50. A total of nine first sliding portions 54 are provided, with three provided separately at three locations in the first sliding groove portion 512A. Of the three first sliding portions 54 arranged side by side, the first sliding portions 54 located in the middle are spaced approximately 120 degrees apart.

[0086] Furthermore, of the three first sliding parts 54 arranged in a row, the first sliding part 54 located in the middle has a larger diameter than the other first sliding parts 54. Therefore, the first sliding part 54 located in the middle slides between the annular guide groove 41 and the first sliding groove 512A (see Figure 21). In other words, the first sliding part 54 is slidably housed in the annular guide groove 41 and the first sliding groove 512A as the mirror housing 50 rotates.

[0087] As described above, since the first sliding portion 54 interposed between the cap portion 40 and the first sliding wall 512 is made of a spherical member, when the mirror housing portion 50 rotates around the Y direction, the first sliding portion 54 slides while rolling between the annular guide groove portion 41 and the first sliding groove portion 512A. In other words, the first sliding portion 54 follows the rotation of the mirror housing portion 50. This makes the rotation of the mirror housing portion 50 around the Y direction smooth.

[0088] Furthermore, since the cap portion 40 is biased toward the mirror housing portion 50 by the biasing portion 33 (annular portion 331) (see Figure 13), the cap portion 40 functions as a thrust bearing at its Y-side end, receiving the load of the mirror housing portion 50 in the Y direction (thrust direction). This reduces the load applied to the camera module 1 in the Y direction.

[0089] The first spacing member 55 is a flat plate member that maintains the spacing between the multiple first sliding members 54, and is positioned between the portion of the first sliding wall 512 corresponding to the first sliding groove 512A and the cap portion 40, so as to be perpendicular to the Y direction. The first spacing member 55 is configured in a circular shape corresponding to the portion of the first sliding wall 512 corresponding to the first sliding groove 512A and the cap portion 40.

[0090] The first spacing portion 55 has three holes 55A, each large enough to accommodate three first sliding portions 54 side by side. Three first sliding portions 54 are positioned in each of the three holes 55A. The portion 551 of the first spacing portion 55 other than the holes 55A divides the annular opening of the first sliding groove portion 512A into multiple partitioned openings, forming a partition portion that allows multiple first sliding portions 54 to be positioned individually. The three holes 55A are positioned to correspond to the multiple partitioned openings in the first sliding groove portion 512A. In other words, the first spacing portion 55 is a flat plate member whose partition portion is formed by three holes 55A.

[0091] As a result, when the mirror housing 50 rotates around a rotation axis along the Y direction, the spacing between each first sliding part 54 is maintained so that it is aligned within a predetermined angular range in the direction of rotation of the mirror housing 50. Consequently, a spacing of approximately 120 degrees is maintained with respect to the center of rotation (the center of the first spacing holding part 55), improving the arrangement balance between each first sliding part 54 and thereby stabilizing the rotation of the mirror housing 50.

[0092] Furthermore, since the first spacing holding portion 55 is made of a separate component from the first sliding groove portion 512A (housing casing 51) and the annular guide groove portion 41 (cap portion 40), there is no need to remake the housing casing 51 or the cap portion 40 when adjusting the position of the first sliding portion 54. Specifically, since it is only necessary to appropriately adjust the position of the hole 55A in the first spacing holding portion 55, the design (work) man-hours required to adjust the position of the first sliding portion 54 can be significantly reduced.

[0093] Furthermore, since the first spacing holding portion 55 is made of a flat plate member, the position of the hole 55A can be easily adjusted, and consequently, the design man-hours can be significantly reduced.

[0094] Furthermore, in this embodiment, since the first sliding groove 512A and the annular guide groove 41 are configured to extend in an annular shape, multiple first sliding parts 54 can be accommodated at once. Therefore, compared to a configuration in which the position of the first sliding part is defined within the groove, it is easier to position each first sliding part 54 within the groove, and the spacing between each first sliding part 54 can be easily adjusted by the first spacing holding part 55.

[0095] Furthermore, since the first spacing holding section 55 is made of a flat plate member, it does not take up width in the Y direction (the direction in which reflected light L2 is emitted), so the size of the housing 51 in the Y direction can be reduced.

[0096] Furthermore, the first spacing holding portion 55 is fixedly positioned relative to the mirror housing portion 50, for example. Specifically, the first spacing holding portion 55 is fixed to the portion corresponding to the first sliding portion 54, for example, with an adhesive.

[0097] Therefore, even if a force is generated that causes the positional relationship between the first sliding part 54 and the mirror housing part 50 to shift, the positional relationship between the first sliding part 54 and the mirror housing part 50 is maintained within a certain range (within the range of hole 55A) because the first spacing holding part 55 is fixed to the mirror housing part 50.

[0098] In this embodiment, since the first sliding portion 54 is a spherical member, when the mirror housing portion 50 rotates around a rotation axis along the Y direction, the first sliding portion 54 slides while rolling. Therefore, even if a force is generated that causes a shift in the positional relationship between the first sliding portion 54 and the mirror housing portion 50, the mirror housing portion 50 can be rotated smoothly.

[0099] Furthermore, since the first sliding groove 512A tapers towards the + side in the Y direction, and the annular guide groove 41 tapers towards the - side in the Y direction, the first sliding part 54 can be supported at two points in each groove. As a result, the position of the first sliding part 54 can be easily stabilized within each groove.

[0100] As shown in Figures 22, 23, and 24, the second sliding portion 56 is a spherical member interposed between the arc-shaped guide groove portion 12B of the ejection wall 12 and the second sliding groove portion 513B of the second sliding wall 513, and by being interposed between it and the ejection wall 12, it forms a surface that supports the mirror housing portion 50. A total of three second sliding portions 56 are provided, separated and provided at three locations in the arc-shaped guide groove portion 12B and the second sliding groove portion 513B. Of the three second sliding portions 56, two adjacent second sliding portions 56 are arranged with a predetermined gap between them.

[0101] The predetermined interval is an angle that can be set according to the shape of the arc in the arc-shaped guide groove 12B and the second sliding groove 513B, and is at least less than 120 degrees. In this embodiment, it is about 90 degrees (see Figure 23).

[0102] Thus, since the second sliding portion 56 interposed between the ejection wall 12 and the second sliding wall 513 is made of a spherical member, when the mirror housing 50 rotates around a rotation axis along the Y direction, the second sliding portion 56 slides while rolling between the arc-shaped guide groove 12B and the second sliding groove 513B. In other words, the second sliding portion 56 is slidably housed in the arc-shaped guide groove 12B and the second sliding groove 513B in accordance with the rotation of the mirror housing 50, and follows the rotation of the mirror housing 50. This makes the rotation of the mirror housing 50 around the Y direction smooth.

[0103] The second spacing member 57 is a flat plate member that maintains the spacing between the multiple second sliding members 56, and is positioned perpendicular to the Y direction, sandwiched between the portion of the second sliding wall 513 corresponding to the second sliding groove 513B and the portion of the ejection wall 12 corresponding to the arc-shaped guide groove 12B. The second spacing member 57 is configured in an arc shape that is convex to the + side in the Z direction, corresponding to the portion of the second sliding groove 513B and the portion of the arc-shaped guide groove 12B.

[0104] The second spacing portion 57 has three holes 57A, each large enough to accommodate one second sliding portion 56. A second sliding portion 56 is positioned in each of the three holes 57A. The portion 570 of the second spacing portion 57 other than the holes 57A divides the annular opening of the second sliding groove portion 513B into multiple partitioned openings, forming a partition portion that allows multiple second sliding portions 56 to be positioned individually. The three holes 57A are positioned to correspond to the multiple partitioned openings in the second sliding groove portion 513B. In other words, the second spacing portion 57 is a flat plate member whose partition portion is formed by three holes 57A. As a result, the second spacing portion 57 holds the three second sliding portions 56 so that they are aligned at equal intervals in the rotational direction of the mirror housing portion 50.

[0105] Therefore, when the mirror housing 50 rotates around a rotation axis along the Y direction, the spacing between each second sliding part 56 is maintained so that it is aligned within a predetermined angular range in the rotational direction of the mirror housing 50. As a result, the arrangement balance between each second sliding part 56 is improved, and the rotation of the mirror housing 50 can be stabilized.

[0106] Furthermore, since the second spacing holding section 57 is made of a separate component from the second sliding groove section 513B (housing casing 51) and the arc-shaped guide groove section 12B (outlet wall 12), there is no need to remake the housing casing 51 or the outlet wall 12 when adjusting the position of the second sliding section 56. Specifically, it is only necessary to appropriately adjust the position of the hole 57A in the second spacing holding section 57, so the design (work) man-hours required to adjust the position of the second sliding section 56 can be greatly reduced.

[0107] Furthermore, since the second spacing holding portion 57 is made of a flat plate member, the position of the hole 57A can be easily adjusted, and consequently, the design man-hours can be significantly reduced.

[0108] Furthermore, in this embodiment, since the second sliding groove 513B and the arc-shaped guide groove 12B are configured to extend in an arc shape, multiple second sliding parts 56 can be accommodated at once. Therefore, compared to a configuration in which the position of the second sliding part is defined within the groove, it is easier to position each second sliding part 56 within the groove, and the spacing between each second sliding part 56 can be easily adjusted by the second spacing holding part 57.

[0109] Furthermore, since the second spacing holding section 57 is made of a flat plate member, it does not take up width in the Y direction (the direction in which reflected light L2 is emitted), so the size of the housing 51 in the Y direction can be reduced.

[0110] Furthermore, the second spacing support section 57 is positioned in an unfixed state relative to the mirror housing section 50 and the ejection wall 12. Unfixed state means that the second spacing support section 57 is not fixed to any part by fastening members such as screws, and is not bonded, welded, or otherwise attached to any part.

[0111] Therefore, if a force is generated that causes a shift in the positional relationship between the second sliding part 56 and the mirror housing part 50, the second sliding part 56 pushes against the edge of the hole 57A of the second spacing holding part 57, and the second spacing holding part 57 also follows the movement of the second sliding part 56.

[0112] As a result, the position of the second spacing holding part 57 between the mirror housing 50 and the ejection wall 12 is stabilized, making it easier for each second sliding part 56 to move to a position where it can easily maintain balance when the mirror housing 50 rotates. In addition, since the second spacing holding part 57 also moves in the rotational direction, the spacing between each second sliding part 56 does not fluctuate, and the rotation of the mirror housing 50 can be stabilized.

[0113] Furthermore, in this embodiment, from the viewpoint of reducing the height of the housing 10, the second sliding groove 513B and the arc-shaped guide groove 12B are configured in an arc shape that is convex to the + side in the Z direction, and the portion of the circle formed by the arc that is negative in the Z direction is cut away. In other words, the rotation center C1 of the mirror housing 50 around the Y direction is located on the negative side in the Z direction than the center of gravity G of the mirror housing 50. For this reason, the second sliding groove 513B and the arc-shaped guide groove 12B are not formed in a circular shape.

[0114] Therefore, the spacing between each second sliding part 56 must be relatively small. If the second sliding groove can be configured in a circular shape, the spacing between the three second sliding parts 56 can be set to 120 degrees, making it easier to balance the arrangement of each second sliding part 56, and thus stabilizing the rotation of the mirror housing 50.

[0115] In contrast, in this embodiment, the spacing between each second sliding part 56 tends to be relatively small, so each second sliding part 56 tends to be biased towards the positive side of the Z direction with respect to the rotation center C1, for example, and there are no second sliding parts 56 on the negative side of the Z direction with respect to the rotation center C1. In other words, in this embodiment, it is difficult to balance the arrangement of the second sliding parts 56.

[0116] However, in this embodiment, the second spacing holding part 57 prevents the positional relationship of each second sliding part 56 from shifting. Therefore, even with a configuration where it is difficult to balance the arrangement of the second sliding parts 56, the rotation of the mirror housing part 50 can be stabilized. As a result, the height of the mirror housing part 50 (housing casing 51) can be reduced.

[0117] Furthermore, in this embodiment, the biasing portion 33 is configured to bias the mirror housing portion 50 toward the + side in the Y direction (towards the ejection wall 12). As a result, the biasing force of the biasing portion 33 presses the second sliding portion 56 against the arc-shaped guide groove portion 12B, making it easier to maintain the arrangement balance of each second sliding portion 56, and consequently stabilizing the rotation of the mirror housing portion 50.

[0118] Furthermore, as described above, since the second spacing holding part 57 follows the movement of the second sliding part 56, the spacing of the second sliding parts 56 is maintained, and each of the second sliding parts 56 can move freely to a position where they can easily balance each other, according to the rotational position of the mirror housing part 50. As a result, the rotation of the mirror housing part 50 can be stabilized.

[0119] Furthermore, since the second sliding groove 513B tapers towards the negative side in the Y direction, and the arc-shaped guide groove 12B tapers towards the positive side in the Y direction, the second sliding part 56 can be supported at two points in each groove. As a result, the position of the second sliding part 56 can be easily stabilized within each groove.

[0120] Next, the mirror holding portion 60 will be described. As shown in Figure 17, the mirror holding portion 60 is the part that holds the mirror element portion 61 and is detachably housed in the mirror housing portion 50. The mirror holding portion 60 is positioned on the mirror guide portion 511 within the mirror housing portion 50 and is configured to slide along the mirror guide portion 511. The mirror holding portion 60 corresponds to the "optical element holding portion" of the present invention.

[0121] As described above, the mirror guide portion 511 is provided with an arc-shaped rotating guide groove portion 511A, and the mirror holding portion 60 is configured to rotate around a rotation axis (second rotation axis) along the X direction by sliding along the rotating guide groove portion 511A.

[0122] As shown in Figures 25 and 26, the mirror holding portion 60 includes a mirror element portion 61, a holding housing 62, a third sliding portion 63, and a holding contact portion 64.

[0123] The mirror element section 61 includes a mirror element (optical element) capable of reflecting incident light L1 and is configured in a substantially rectangular shape. The rotation guide groove section 511A has an arc shape that is convex diagonally toward the negative side in the Z direction and the negative side in the Y direction, so the mirror holding section 60 is positioned on the rotation guide groove section 511A and is positioned at an inclination with respect to the Z and Y directions (see Figure 28, etc.).

[0124] In other words, the mirror element 61 is arranged to bend the incident light L1 so that it travels in one direction (+ side) in a direction different from the direction along the incident light L1 (Z direction) (Y direction). The mirror element 61 corresponds to the "optical element" of the present invention.

[0125] As shown in Figure 25, the holding housing 62 is the part that holds the mirror element portion 61 and slides the mirror guide portion 511, and has a main body portion 621 and a magnet holding portion 622.

[0126] The main body portion 621 is the part that fixes the mirror element portion 61 and has a fixing surface 621A to which the mirror element portion 61 can be fixed. The main body portion 621 is positioned on the mirror guide portion 511 such that the fixing surface 621A faces the positive side in the Z direction. The mirror element portion 61 is fixed to the fixing surface 621A by adhesive, for example. Note that the mirror element portion 61 may be fixed to the main body portion 621 in any way.

[0127] As shown in Figure 26, a third sliding groove 621B is provided on the surface of the main body 621 facing the negative side in the Z direction. The third sliding groove 621B is configured in an arc shape that is convex to the negative side in the Z direction so that it can be positioned along the rotation guide groove 511A described above. The third sliding groove 621B has a shorter arc length than the rotation guide groove 511A (guide surface) of the mirror guide portion 511 and is a guided surface that is guided by the rotation guide groove 511A.

[0128] The third sliding groove 621B is provided at both ends of the main body 621 in the X direction and is positioned opposite the rotation guide groove 511A in the Z direction (see Figure 27). The third sliding groove 621B has a groove shape that tapers towards the bottom (the + side in the Z direction).

[0129] The third sliding portion 63 is a spherical member interposed between the rotating guide groove 511A and the third sliding groove 621B. Three third sliding portions 63 are provided at each end in the X direction. The three third sliding portions 63 on one side (+ side or - side) in the X direction are arranged in a line along the groove shape of the third sliding groove 621B.

[0130] As described above, the third sliding portion 63 interposed between the rotating guide groove 511A and the third sliding groove 621B is made of a spherical member. Therefore, when the mirror holder 60 rotates around a rotation axis along the X direction, the third sliding portion 63 slides between the rotating guide groove 511A and the third sliding groove 621B while rolling (see Figure 27). This allows the rotation of the mirror holder 60 around the rotation axis along the X direction to be smooth.

[0131] Furthermore, a holding contact portion 64 is attached to the surface of the main body portion 621 facing the negative side in the Z direction. The holding contact portion 64 is provided between the third sliding groove portions 621B at both ends in the X direction and is positioned to be in contact with the resonant portion 511B of the mirror guide portion 511 described above (see Figure 17). The holding contact portion 64 applies preload to the mirror holding portion 60, causing it to rotate by contacting the vibrating resonant portion 511B.

[0132] In other words, the resonant portion 511B and the holding contact portion 64 constitute an ultrasonic motor that acts as a drive unit (second drive unit) for rotational driving of the mirror holding portion 60 around the X direction, that is, for driving the mirror holding portion 60 to move on the mirror guide portion 511. Note that the second drive unit may be something other than an ultrasonic motor, such as a VCM.

[0133] Furthermore, as shown in Figure 28, when the mirror holding portion 60 is rotated to its maximum extent towards the positive Z side, the main body portion 621 moves to a position where its end on the positive Z side faces the aforementioned restricting cover portion 52 and does not come into contact with the first restricting wall 521A (see dashed line). The presence of the first restricting wall 521A restricts the movement of the main body portion 621 towards the positive Z side even if the main body portion 621 moves excessively or if an external force is applied to move it towards the positive Z side.

[0134] As shown in Figures 25 and 26, the magnet holding portion 622 is provided at both ends of the main body portion 621 in the X direction, and protrudes from each of these ends to the positive side in the Z direction and the positive side in the Y direction.

[0135] As shown in Figures 28 and 29, the magnet holder 622 is positioned opposite the second restricting wall 522A of the restricting cover 52 in the Z direction. The amount of the magnet holder 622 protruding to the + side in the Z direction is such that it does not come into contact with the second restricting wall 522A. The presence of the second restricting wall 522A restricts the movement of the main body 621 to the + side in the Z direction, even if an external force is applied to move the main body 621 to the + side in the Z direction.

[0136] Furthermore, as shown in Figure 29, the magnet holder 622 faces the restricting portion 514A on the side wall 514 in the Y direction, and when the mirror holder 60 rotates to its maximum extent towards the + side in the Y direction, the end on the + side in the Y direction moves to a position where it does not come into contact with the restricting portion 514A (see dashed line). The presence of the restricting portion 514A restricts the movement of the mirror holder 60 towards the + side in the Y direction, even if the mirror holder 60 moves excessively or if an external force is applied to move it towards the + side in the Y direction.

[0137] As shown in Figures 25 and 26, the magnet holder 622 is provided with a magnet portion 623. The magnet portion 623 has a first pole 623A and a second pole 623B that are arranged adjacent to each other in the Y direction. The first pole 623A is a south pole magnet, and the second pole 623B is a north pole magnet.

[0138] As shown in Figure 30, the portion of the magnet holder 622 that holds the magnet portion 623 is located opposite the yoke arrangement portion 514B in the housing 51 in the Z direction. The magnet holder 622 has a shape on its Z-side surface that follows the yoke arrangement portion 514B (yoke portion 515). Specifically, the magnet holder 622 is movable along the first surface 515A of the yoke portion 515 as the mirror holder 60 moves, and has a second surface 623C that has the same curvature as the first surface 515A (rotation guide groove portion 511A).

[0139] The magnet holding portion 622 holds the magnet portion 623, so that the magnet portion 623 is positioned opposite the yoke portion 515 in the yoke arrangement portion 514B.

[0140] As a result, the magnet section 623 and the yoke section 515 attract each other magnetically. In other words, the magnet section 623 and the yoke section 515 generate a pre-pressure that magnetically pulls the mirror holding section 60 toward the housing 51.

[0141] As a result, the mirror holding part 60 remains attracted to the housing 51 even when it is rotated or when an external force is applied, so that the mirror element part 61 can be securely held within the housing 10.

[0142] Incidentally, as shown in Figures 28 and 29, in this embodiment, from the viewpoint of simplifying and reducing the height of the housing 10, the curved shape formed by the rotating guide groove 511A and the third sliding groove 621B is set such that the amount of movement of the mirror holding portion 60 in the Y direction is relatively large, and the amount of movement of the mirror holding portion 60 in the Z direction is relatively small. Therefore, the rotation center C2 of the rotation axis of the mirror holding portion 60 in this embodiment is located outside the housing 51.

[0143] To achieve this, the mirror holder 60 is positioned in a manner that does not have a fixed point on the housing 51, or is positioned in a manner that has relatively simple holding points or engagement points. In this embodiment, the mirror holder 60 is positioned in a manner that does not have a fixed point on the housing 51.

[0144] In other words, as the housing 10 is simplified and made lower in height, the movement mechanism of the mirror holding part 60 must be simplified, which makes the holding part of the mirror holding part 60 (mirror element part 61) more fragile, and consequently makes the mirror holding part 60 more likely to come off the housing 51.

[0145] In this embodiment, the magnetic attraction between the magnet portion 623 and the yoke portion 515 makes it possible to securely hold the mirror holding portion 60 within the housing 10. In other words, in this embodiment, even if the holding portion of the mirror holding portion 60 is fragile, the mirror holding portion 60 can be securely held within the housing 51. As a result, in this embodiment, the housing 10 can be easily simplified and made lower in profile.

[0146] Furthermore, in this embodiment, since magnetically attractive pre-pressure is generated at the opposing portions of the magnet portion 623 and the yoke portion 515, pre-pressure can be generated only at the opposing portions of the rotating guide groove portion 511A and the third sliding groove portion 621B. In other words, the magnet portion 623 and the yoke portion 515 can generate pre-pressure toward the outward direction in the normal direction of the rotating guide groove portion 511A at the opposing position of the rotating guide groove portion 511A and the third sliding groove portion 621B, which are displaced as the mirror holding portion 60 moves.

[0147] Therefore, in this embodiment, a simple configuration can be achieved without providing a component that continuously applies biasing force, such as a biasing member, and the mirror holding portion 60 can be securely held within the housing 51.

[0148] Furthermore, since the magnet portion 623 slides along the first surface 515A of the yoke portion 515, the magnet portion 623 can move smoothly along the first surface 515A of the yoke portion 515 even when the mirror holding portion 60 moves.

[0149] Furthermore, since the first surface 515A of the yoke portion 515 and the second surface 623C of the magnet portion 623 have the same curvature as the rotation guide groove portion 511A, the movement of the magnet portion 623 on the yoke portion 515 can be made even smoother.

[0150] Furthermore, the magnet holding portion 622 is arranged along a pair of side walls 514 of the housing 51. The position detection hole 514C described above is formed in the side wall 514 on the + side in the X direction, and the position detection portion 532A described above is provided at a position corresponding to the position detection hole 514C.

[0151] As shown in Figure 30, the position detection unit 532A is positioned to detect the magnetic force of the magnet unit 623 and detects the change in the magnetic position of the magnet unit 623 of the magnet unit 622 based on the movement of the mirror holding unit 60. In other words, the position detection unit 532A detects the position of the mirror holding unit 60.

[0152] As a result, the position of the mirror holder 60 can be controlled with high precision. Furthermore, in relation to the yoke 515, the magnet 623 that attracts the mirror holder 60 and the housing 51 can also be used as a magnet for position detection. As a result, there is no need to provide a separate magnet for position detection, which reduces the number of parts and further simplifies the configuration.

[0153] Next, the power supply path section 70 will be described. As shown in Figure 31, the power supply path section 70 electrically connects the substrate section 20 and the mirror housing section 50, and constitutes a power supply path between the substrate section 20 and the mirror housing section 50.

[0154] The power supply path section 70 is used, for example, to supply power to the resonant section 511B and the position detection section 532A in the mirror housing section 50, and a total of six are provided, three on the positive side and three on the negative side. The three power supply path sections 70 on the positive side are, for example, located on the negative side in the X direction relative to the mirror housing section 50, and the three power supply path sections 70 on the negative side are, for example, located on the positive side in the X direction relative to the mirror housing section 50. In other words, the power supply path sections 70 are provided on both ends of the mirror housing section 50 in the X direction, which is perpendicular to the Z and Y directions, respectively.

[0155] Note that in Figure 31, etc., only the negative (-) power supply path 70 in the X direction is shown. The positive (+) power supply path 70 in the X direction has substantially the same shape as the negative (-) power supply path 70 in the X direction, so its description is omitted. Also, although terminal 12C is inserted into the outlet wall 12, in Figure 31, etc., the outlet wall 12 is not shown, and only terminal 12C is shown.

[0156] As shown in Figures 31 and 32, the power supply path section 70 extends from the positive end in the Y direction of the housing 10, where the terminal 12C connected to the input / output terminal 21A of the aforementioned circuit board section 20 is located, to the negative end in the Y direction, where the first power supply terminal 531A of the housing side circuit board section 53 and the path holding section 512B of the mirror housing section 50 are located. In other words, the power supply path section 70 extends across both ends of the mirror housing section 50 in the Y direction, and extends to connect the terminal 12C (the terminal on the circuit board section 20 side) and the first power supply terminal 531A (the terminal on the mirror housing section 50 side), which are spaced apart in the Y direction.

[0157] The power supply path section 70 extends from the aforementioned terminal 12C, which is connected to the input / output terminal 21A of the circuit board section 20, in a direction along the Y direction, and is connected to the first power supply terminal 531A of the housing side circuit board section 53 of the mirror housing section 50.

[0158] The power supply path section 70 is configured to partially include a spring section. Specifically, the power supply path section 70 is composed of a first wire section 71A, a first spring section 72A, a second wire section 71B, a second spring section 72B, and a third wire section 71C.

[0159] The first wire section 71A and the third wire section 71C are wire sections located at both ends in the Y direction of the power supply path section 70, respectively, and are connected to the input / output section (terminal 12C or first power supply terminal 531A) of the substrate section 20 or the housing side substrate section 53 of the mirror housing section 50. A damper member 73 is provided at the connection portion between the first wire section 71A and the third wire section 71C and the input / output section.

[0160] The first wire section 71A is connected to the first spring section 72A and is shorter than the third wire section 71C. The third wire section 71C is connected to the second spring section 72B.

[0161] The second wire section 71B connects the first spring section 72A and the second spring section 72B, and is longer than the first wire section 71A and the third wire section 71C.

[0162] The first spring section 72A and the second spring section 72B are coil sections made of coil springs. The first spring section 72A is positioned between the first wire section 71A and the second wire section 71B, and the second spring section 72B is positioned between the second wire section 71B and the third wire section 71C. The second spring section 72B is longer than the first spring section 72A.

[0163] The three power supply path sections 70 on one side (+ side or - side) in the X direction are arranged side by side in the Z direction and are positioned so as not to interfere with each other. Specifically, of the three power supply path sections 70, the spring sections 72A and 72B of two adjacent power supply path sections 70 in the Z direction are positioned such that their positions in the Y direction are different from each other.

[0164] In other words, for example, the power supply path sections 70 on the most positive and most negative sides in the Z direction have the first wire section 71A connected to terminal 12C of the substrate section 20 and the third wire section 71C connected to the path holding section 512B of the mirror housing section 50. Also, the power supply path section 70 located in the middle in the Z direction has the third wire section 71C connected to terminal 12C of the substrate section 20 and the first wire section 71A connected to the path holding section 512B of the mirror housing section 50.

[0165] Furthermore, a position fixing portion 74 is provided in the center of the three power supply path portions 70 on one side in the X direction, in the Y direction. The position fixing portion 74 is for maintaining the relative positions of the three power supply path portions 70 within a certain range. The position fixing portion 74 is plate-shaped and configured to engage with each portion of the second wire portion 71B. The position fixing portion 74 corresponds to the "maintenance portion" of the present invention.

[0166] Furthermore, damper members 75 are provided at the engagement portion with the position fixing portion 74 in the power supply path sections 70 on the most positive and most negative sides in the Z direction. In addition, in the power supply path section 70 in the middle of the Z direction, the engagement portion with the position fixing portion 74 is free. Specifically, a portion 74A corresponding to the power supply path section 70 in the middle of the Z direction is cut out of the position fixing portion 74, and the power supply path section 70 in the middle of the Z direction passes through this portion 74A.

[0167] Incidentally, as shown in Figures 33 and 34, when the mirror housing 50 rotates around its axis of rotation in the Y direction, the first power supply terminal 531A of the mirror housing 50 moves to the + or - side in the Z direction (direction of movement). In other words, the mirror housing 50 moves such that the first power supply terminal 531A, which is the connection part of the power supply path 70, moves closer to or away from the substrate 20.

[0168] For example, suppose the mirror housing 50 rotates from the position shown in Figure 33 so that its X-side end is raised, and the X-side first power supply terminal 531A moves to the Z-side. Note that when the mirror housing 50 rotates so that its X-side end is raised, the X-side first power supply terminal 531A moves to the Z-side.

[0169] As a result, as shown in Figure 34, the first power supply terminal 531A is positioned on the positive side in the Z direction after the mirror housing 50 has moved, compared to its position before the movement (see Figure 33). Therefore, after the mirror housing 50 has moved (see Figure 34), the spring portions 72A and 72B are extended longer than they were in their state before the movement (see Figure 33).

[0170] In this case, for example, if the circuit board and the mirror housing are connected using a leaf spring as the power supply path, the leaf spring has a relatively strong reaction force, which can easily hinder the rotation of the mirror housing.

[0171] In contrast, in this embodiment, the power supply path section 70 extends in the Y direction, and the spring sections 72A and 72B are made of coil springs, so the spring sections 72A and 72B can easily expand and contract in accordance with the rotation of the mirror housing section 50.

[0172] In other words, because the spring sections 72A and 72B have relatively low reaction force, they can absorb the positional shift between the base plate section 20 and the mirror housing section 50 before and after movement, which is caused by the rotation of the mirror housing section 50. As a result, the rotation of the mirror housing section 50 can be made smooth while power is supplied to the housing-side base plate section 53 of the mirror housing section 50.

[0173] By the way, if all of the power supply path sections 70 are configured so that the spring sections 72A and 72B are at the same position in the Y direction, then, for example, as shown in Figure 34, when the mirror housing section 50 moves to a position where the spring sections 72A and 72B are extended, the two adjacent power supply path sections 70 tend to get closer to each other, making it easier for their spring sections to interfere with one another.

[0174] In contrast, in this embodiment, the positions in the Y direction of the spring portions 72A and 72B of two adjacent power supply path sections 70 in the Z direction are different from each other. Therefore, when the spring portions 72A and 72B deform based on expansion and contraction, the spring portions of the two adjacent power supply path sections 70 do not interfere with each other. As a result, power can be supplied accurately by the two power supply path sections 70. It is also possible to provide spring portions throughout the entire power supply path section 70 by reducing the winding diameter of the spring portion of the power supply path section 70. In this configuration, the distance between the spring portions of two adjacent power supply path sections can be widened compared to the configuration in which the winding diameter is not reduced, without changing the distance between each power supply path section. Therefore, interference between spring portions can be suppressed, and the reaction force can be weakened compared to the configuration in which only a portion of the spring portion is present.

[0175] Furthermore, since each power supply path section 70 can be placed as close together as possible, the space required for the power supply path sections 70 can be reduced, which in turn allows for miniaturization and a reduction in the height of the mirror housing section 50.

[0176] Furthermore, by providing the position fixing part 74, the positional relationship of the three power supply path parts 70 in the Z direction can be maintained within a certain range, thereby further suppressing interference between the three power supply path parts 70.

[0177] Furthermore, the arrangement of the springs in the middle power supply path section 70 in the Z direction is different from that of the other two power supply path sections 70. Therefore, the deformation of the springs when the mirror housing section 50 rotates is different from that of the other two power supply path sections 70. Consequently, if this power supply path section 70 is fixed to the position fixing section 74, as with the other two power supply path sections 70, it will affect the movement of the power supply path section 70 due to the rotation of the mirror housing section 50.

[0178] In contrast, in this embodiment, only the power supply path section 70 in the middle of the Z direction is provided in an unfixed state to the position fixing section 74. As a result, it is possible to suppress the influence of the movement of the power supply path section 70 due to the rotation of the mirror housing section 50 on the other two power supply path sections 70.

[0179] In the above embodiment, the biasing portion 33 was configured to have a symmetrical shape in the Z direction such that the arm portion 332 on the positive side in the Z direction and the arm portion 332 on the negative side in the Z direction were the same shape (see Figure 10). However, the present invention is not limited to this, and the biasing portion does not have to be configured to have a symmetrical shape in the Z direction.

[0180] For example, as shown in Figure 35, the arm portion 332A on the positive side in the Z direction and the arm portion 332B on the negative side in the Z direction of the biasing portion 33 may have different shapes. The arm portion 332A on the positive side in the Z direction has a straight portion A1 and a curved portion A2.

[0181] The straight section A1 extends from the positive end in the Z direction of the annular section 331 toward the end of the biasing section 33 in the X direction. The end of the straight section A1 extends to the vicinity of the connection point between the two arm sections 332A and 332B.

[0182] The curved section A2 curves from the end of the straight section A1 opposite to the annular section 331, towards the negative side in the Z direction, then towards the annular section 331 in the X direction, and then curves away from the annular section 331 in the X direction to connect to the connecting section 333.

[0183] The arm portion 332B on the negative side in the Z direction curves from the portion of the annular portion 331 near the positive side in the Z direction at the X-direction end, then curves toward the positive side in the Z direction, and connects to the connecting portion 333.

[0184] With this shape, the biasing force of the biasing portion 33 is greater on the positive side in the Z direction than the rotation center C1 of the mirror housing portion 50 than the biasing force of the portion on the negative side in the Z direction than the rotation center C1.

[0185] In the above embodiment, the rotation center C1 of the mirror housing 50 is located on the negative side in the Z direction relative to the center of gravity G of the mirror housing 50. As a result, the negative side in the Z direction of the circle forming the arc of the second sliding groove 513B and the arc-shaped guide groove 12B is removed. Therefore, in the mirror housing 50, at the negative end in the Y direction (the cap portion 40), the load applied on the positive side in the Z direction relative to the rotation center C1 is greater than the load applied on the negative side in the Z direction relative to the rotation center C1.

[0186] Therefore, by using the biasing part 33 shown in Figure 35, the biasing force on the positive side in the Z direction relative to the rotation center C1 can be increased, making it easier for the cap part 40 to receive the load in the Y direction in a more stable manner, and consequently stabilizing the rotation of the mirror housing part 50.

[0187] Furthermore, in the above embodiment, the hole 55A of the first spacing holding portion 55 was sized to accommodate three first sliding portions 54, but the present invention is not limited to this, and for example, as shown in Figure 36, it may be sized to accommodate only one first sliding portion 54.

[0188] The hole 55B of this first spacing holding portion 55 has a diameter approximately the same as that of one first sliding portion 54, and has a diameter large enough for one first sliding portion 54 to rotate within the hole 55B.

[0189] This configuration allows the spacing between each of the first sliding parts 54 to be maintained at equal intervals.

[0190] Furthermore, although the first spacing holding portion 55 was fixed to the mirror housing portion 50 in the above embodiment, the present invention is not limited thereto, and may be positioned in an unfixed state relative to the mirror housing portion 50 and the cap portion 40.

[0191] Furthermore, by leaving the first spacing holding part 55 in an unfixed state as shown in Figure 36, the first spacing holding part 55 can more easily follow the movement of the first sliding part 54.

[0192] Furthermore, in the above embodiment, the second spacing holding portion 57 was positioned in an unfixed state relative to the mirror housing portion 50 and the ejection wall 12, but the present invention is not limited thereto, and may be fixed to the mirror housing portion 50, for example, as shown in Figure 37.

[0193] The second spacing portion 57 has an arc portion 571 and a protruding portion 572. The arc portion 571 is configured in an arc shape that is convex to the + side in the Z direction and is provided at a position corresponding to the second sliding groove portion 513B of the second sliding wall 513. The arc portion 571 is provided with a hole 57A in which the second sliding portion 56 is arranged.

[0194] The protruding portion 572 is provided so as to extend outwards from the arc portion 571 toward both ends in the X direction. The protruding portion 572 is provided with an engagement hole 57B. In addition, at positions corresponding to the engagement holes 57B at both ends of the second sliding wall 513 in the X direction, there are protruding portions 513C that project toward the + side in the Y direction. The engagement hole 57B engages with the protruding portion 513C, thereby fixing the second spacing holding portion 57 to the mirror housing portion 50.

[0195] Furthermore, by positioning the second spacing retainer 57 in a fixed state, the spacing between each hole 57A may be set to the maximum spacing. The maximum spacing is set appropriately according to the second sliding groove 513B. In this way, the spacing (angle) of each second sliding part 56 can be brought as close to 120 degrees as possible.

[0196] Furthermore, in the configuration shown in Figure 37, the position of the second sliding portion 56 is fixed in conjunction with the fixing of the second spacing holding portion 57. However, the present invention is not limited to this, and a configuration that allows movement of the second sliding portion 56 is also possible.

[0197] For example, as shown in Figure 38, the hole 57C provided in the second spacing holding portion 57 (arc portion 571) is formed to be large enough to accommodate, for example, three second sliding portions 56.

[0198] Furthermore, in the above embodiment, three holes 57A were provided in the second spacing holding portion 57 where the second sliding portion 56 is positioned. However, the present invention is not limited to this, and three or more holes may be provided.

[0199] For example, as shown in Figure 39, the second spacing member 57 is provided with five holes 57A. The holes 57A are spaced equally apart in the rotational direction between two adjacent holes 57A.

[0200] With this configuration, it becomes possible to adjust the hole 57A into which the second sliding part 56 is inserted as appropriate, and it also becomes possible to arrange three or more second sliding parts 56 (for example, five to match the hole 57A).

[0201] Furthermore, although the first and second spacing holding portions in the above embodiment had holes, the present invention is not limited thereto, and may also have a configuration with notches on which sliding portions can be arranged.

[0202] Furthermore, in the above embodiment, each groove had a shape that tapered towards it, but the present invention is not limited to this, and the groove does not have to have such a shape.

[0203] Furthermore, although the sliding parts were configured in a spherical shape in the above embodiment, the present invention is not limited thereto, and any shape is acceptable as long as it is possible to slide between the movable part and its opposing part.

[0204] Furthermore, in the above embodiment, the yoke portion 515 was arranged on the mirror housing portion 50 side and the magnet portion 623 was arranged on the mirror holding portion 60 side, but the present invention is not limited to this. For example, the magnet portion may be arranged on the mirror housing portion side and the yoke portion may be arranged on the mirror holding portion side.

[0205] Furthermore, in the above embodiment, the shape of the opposing surfaces of the yoke portion 515 and the magnet portion 623 was matched to the shape of the guide surface in the mirror guide portion 511, but the present invention is not limited thereto. For example, the shape of the opposing surfaces of the yoke portion and the magnet portion can be any shape as long as it does not obstruct the guidance of the mirror holding portion in the mirror guide portion.

[0206] Furthermore, in the above embodiment, the magnet unit that generates the pre-pressure to attract the mirror housing unit and the mirror holding unit also served as the magnet for position detection. However, the present invention is not limited to this, and a separate magnet unit for position detection may be provided.

[0207] Furthermore, although a third sliding portion was interposed between the mirror guide portion and the mirror holding portion in the above embodiment, the present invention is not limited thereto, and as long as the mirror guide portion can guide the mirror holding portion, the third sliding portion does not need to be interposed.

[0208] Furthermore, in the above embodiment, the mirror guide portion and the mirror holding portion were magnetically attracted to each other, but the present invention is not limited thereto, and for example, a biasing member or the like may be used to attract the mirror guide portion and the mirror holding portion and generate a pre-pressure.

[0209] Furthermore, in the above embodiment, the mirror holding portion 60 was positioned without having a fixed point in the housing casing 51, but the present invention is not limited thereto, and the mirror holding portion 60 may have a fixed point within the housing casing 51.

[0210] Furthermore, in the above embodiment, the power supply path 70 extended across both ends of the mirror housing 50 in the Y direction, but the present invention is not limited to this, and as long as it extends in the Y direction, it does not have to extend across both ends.

[0211] Furthermore, in the above embodiment, three power supply path sections 70 were provided on both the positive and negative sides. However, the present invention is not limited to this, and the number of power supply path sections 70 may be appropriately changed depending on the number of components to be powered.

[0212] Furthermore, in the above embodiment, the position fixing part 74 held only the central power supply path part 70 in a free state, but the present invention is not limited to this, and only the central power supply path part 70 may be fixed.

[0213] Furthermore, in the above embodiment, the power supply path 70 extended in a direction along the Y direction, but the present invention is not limited thereto. As long as the mirror housing rotates around a rotation axis along the Y direction and the power supply path includes a coil spring (displacement part), it does not need to extend in a direction along the Y direction.

[0214] Furthermore, although the above embodiment provided separate drive control unit, lens drive control unit, and imaging control unit, the present invention is not limited thereto, and at least two of the drive control unit, lens drive control unit, and imaging control unit may be composed of a single control unit.

[0215] Furthermore, for example, in the above embodiment, a smartphone, which is a mobile terminal with a camera, was described as an example of a camera-mounted device equipped with a camera module 1. However, the present invention can be applied to a camera-mounted device having a camera module and an image processing unit that processes image information obtained by the camera module. Camera-mounted devices include information equipment and transportation equipment. Information equipment includes, for example, mobile phones with cameras, notebook computers, tablet terminals, portable game consoles, webcams, drones, and in-vehicle devices with cameras (e.g., rearview monitors, drive recorders). Transportation equipment includes, for example, automobiles and drones.

[0216] Figures 40A and 40B show a vehicle V as a camera-mounted device equipped with an in-vehicle camera module VC (Vehicle Camera). Figure 40A is a front view of vehicle V, and Figure 40B is a rear perspective view of vehicle V. Vehicle V is equipped with the camera module 1 described in the embodiment as the in-vehicle camera module VC. As shown in Figures 40A and 40B, the in-vehicle camera module VC can be mounted, for example, on the windshield facing forward or on the rear gate facing backward. This in-vehicle camera module VC is used for purposes such as a backup monitor, a drive recorder, collision avoidance control, and autonomous driving control.

[0217] Furthermore, the above embodiments are merely examples of how the present invention may be implemented, and the technical scope of the present invention should not be interpreted as being limited by them. In other words, the present invention can be implemented in various forms without departing from its gist or its main features. For example, the shape, size, number, and material of each part described in the above embodiments are merely examples and can be modified as appropriate. [Industrial applicability]
